Slated to cost over $ 25 billion and take 5 years to complete, this incredible proposal starts a with a living sphere that spans over 1,500 feet below the surface of the ocean.

Designed by the Shimizu Corp’s, the spherical portion of the so-called Ocean Spiral forms a residential and commercial core from which a winding path spirals 9 further miles into the deep, ultimately terminating at the ocean floor.

Occupants would live and work both in triangular neighborhoods along the periphery as well as within a tapering, hourglass-shaped, skyscraper-like segment stretching up from the bottom to the top of the sphere’s center.

The ‘Earth Factory’ portion of the project below is set to use generate eco-friendly energy from temperature differentials and organically-driven chemical conversion processes.

For anyone wondering just when they can expect this marvel to materialize: its would-be creators concede the technology is just not in place yet to make it a reality, but hope and presume it will be soon.

5 Tips for Underwater Photography Without Spending a Fortune

26 Oct

Underwater photography is so much fun that it will take you to the farthest reaches of the world, inspire you to buy thousands of dollars of dive gear, and thousands of dollars more worth of underwater photography gear. It can also make you want to throw your underwater camera rig against the side of the dive boat, then into the water, then dive down and get it just so you can throw it to the bottom again. Spending six hours of planning and preparation just to find out the water is murky or that the fish aren’t there, or that the manta rays aren’t at their feeding station is incredibly frustrating.

Diver Swimming

On the other hand, you can see such beautiful things, experience such euphoria when everything stays in place long enough to compose your shot properly, and discover the joy of finding out that it was all wonderfully in focus when you review your images on the computer. You can capture some of nature’s finest and most majestic moments in a way that most people will never see. You can open your audience’s eyes to the beauty of nature from a perspective that those who don’t SCUBA dive may never be able to experience.

There are many hurdles to being an underwater photographer. The first is the diving skill. There is no substitute for being a proficient and safe diver. You must be able to maintain neutral buoyancy and safely complete all dives.

The next challenge is the gear. As if photography wasn’t a gear intensive enough activity, to do it underwater you need special housings, dome ports, and even strobes.

Bridge 2

Don’t let these hurdles stop you. Underwater photography is worth every bit of pain and sacrifice when you become proficient.

The problem most beginners face is that there’s really no good ambient light because the colors are filtered by the water. In my
experience, around 10 feet, you’ve lost any good color of light and you get the characteristic baby blue, boring pictures. So, you’re left with a conundrum – buy expensive strobes or have your pictures stink … or are you?

What if there was a better way to get underwater images without a strobe; one that didn’t require an expensive setup and the risky
business of bringing your DSLR into the water? What if you could learn a few simple but powerful techniques to let your underwater
images sing without a strobe?

Here’s what I recommend, go big or go black and white. Go big means dive into the deep end (pun intended) and buy the housings and strobes (you’re not planning on using just one are you?). This is an expensive but professional option. The second option is to go black and white.

Bow Looking Down

If you compose and think about getting good black and white images your underwater results will be very compelling, easy to post-process, and simple to take. Some rules to live by include:

  1. Safety first (enough said)
  2. Don’t try for little fast moving, colorful fish – these won’t turn out without a strobe
  3. Look for compelling images of your dive buddies or large objects (like wrecks, turtles, and sharks – but no touching please)
  4. Get close
  5. Look for long lines (like a descent line) and compose them across the screen (not vertical please) with a good subject (like other divers)

Bow Crowss View

If you start with these five simple rules you’ll be able to shoot hang-it-on-the-wall quality images without an expensive strobe or underwater-housing. Who knows, you may even like shooting underwater so much you get a full setup one day. If you do, remember, throwing your gear never solves anything – expect exposure problems with your strobes, rig floods, focus problems, corroded buttons, cracked seals, or backscatter from murky water.

Now you’re ready to take your camera and start shooting underwater. Using a fisheye lens will make your life much easier when you start out. It makes issues like focus and composition much easier to get right. It also lends itself very well to black and white images.

Drowned Towns: 10 Underwater Ghost Cities & Buildings

10 Mar

[ By Steph in Global & Travel & Places. ]

Drowned Towns Main

Mildewed crosses, lonely spires, barely-visible stone foundations and rusting bed frames are all that’s left to show for these 10 intentionally submerged towns and structures from India to Massachusetts. When additional water and power is needed to provide for growing populations, small villages often have to be sacrificed, and while some were demolished before their remains were flooded, others can still be seen as ghostly visions wavering beneath the surface.

Potosi, Venezuela

Drowned Towns Potosi 1

Drowned Towns Potosi 2

Another town lost to the creation of a hydroelectric dam, Potosi was abandoned in 1985, its residents relocating and leaving their former homes to be filled with water. For 20 years, all that was visible of the Veneuzuelan town was a single mildewed cross topping a drowned church, but by the year 2010, the waters began to recede and the town slowly reappeared. The gothic church that was once submerged is visible again due to droughts and water shortages, erosion and water damage making it appear much older than it really is.

Steeple Tombstone: Curon Venosta, Italy

Drowned Towns Steeple Tomb 1

Drowned Towns Steeple Tomb 2

A single spire marks the location of an entire town lost beneath Lago di Resia. The alpine village of Curon Venosta was flooded soon after World War II when officials decided to merge three pre-existing lakes into one to create a hydroelectric dam. Before it was inundated, the town – which included 163 houses and nearly 1,300 acres of land planted with fruit – was filled with sand. The bell tower, which was built in the 14th century, was left intact as a memorial, and can be reached on foot in the winter when the lake freezes over.

Vilarinho da Furna, Portugal

Drowned Towns Vilarinho da Furna

In 1972, the creation of a new dam meant the ancient Vilarinho da Furna was lost beneath the water. The Portuguese village, which dates back to Roman times, was home to almost 300 people inhabiting 80 houses before it was submerged; the property still belongs to their descendants, and reappears every now and then when the reservoir levels fall. The community was unique in that it had a communitarian social system with a council called the Junta made up of a single member from each family, a practice dating back to the Visigoths. When the villagers left they took as much as they could, creating their own road to transport things like rocks and roof tiles to their new homes. Some of those rocks were used to build a museum commemorating Vilarinho da Furna, which contains a collection of clothing, agricultural tools, and paintings depicting daily life in the village.

Jal Mahal, Jaipur, India

Drowned Towns Jal Mahal 1

Drowned Towns Jal Mahal 2

The Water Palace of Jaipur, India sits in the center of Man Sagar Lake. No one knows exactly when it was built, but it’s believed that the red sandstone structure is at least 300 years old and was constructed before damming created the lake, submerging its lower four stories. When the lake is full, only the top level can be reached, and only by boa. At night, the place is illuminated with floodlights like some kind of hallucinatory ghost structure. The palace was recently restored and is now open to visitors.

Excel at Underwater Photography Like You’re Part Fish

18 Dec

Underwater photography is an acquired taste that is both an art form and a means of obtaining data. Usually, scuba divers are the ones taking underwater photos, but this art form can also be carried out while diving on surface supply, just swimming, snorkeling or safely inside a submersible. While underwater photography can be understandably difficult to successfully carry out, Continue Reading

Sleep with the Fishes: Floating Underwater Hotel Room

26 Nov

[ By Steph in Global & Travel & Places. ]

Underwater Hotel Room Manta Resort 1

Watch eerily illuminated sea creatures swim past your windows at night as you fall asleep on your own ‘private floating island,’ an underwater hotel room at the Manta Resort. This special getaway is a two-story floating wooden structure with a submerged bedroom, a surface-level deck that lets you dive into the sea, and a rooftop lounge area.

Underwater Hotel Room Manta Resort 2

Underwater Hotel Room Manta Resort 5

Located off the eastern coast of Africa near Pemba Island, the artificial floating island has virtually everything you’d want from a resort – as long as you’re okay with near-total seclusion. That means no other guests, but also no waiters or other attendees. You might be okay with that, given the scenery – but no worries, you can always take a boat back to the main resort to enjoy the restaurant and spa.

Underwater Hotel Room Manta Resort 4

Designed by Swedish firm Genberg Underwater Hotels, the three-story structure is envisioned as a private getaway for a couple. It’s anchored to the sea floor from its four corners so it won’t float away, bobbing gently on the sea. Guests can enjoy views of all sorts of marine life, and coral reefs. After dark they’re still visible thanks to underwater spotlights beneath each window.
